Virtualization - Compaq BL10e - HP ProLiant - 512 MB RAM Introduction Manual

Technology Description
Power Power capping allows administrators to constrain the BTUs per
capping server blade or enclosure, enabling the enclosure to fit in an
existing rack power envelope. A simple power cap allows devices
to power on until power use reaches the specified power cap and
then prevents any more devices from powering on.
The optional Enclosure Dynamic Power Capping setting in the OA
enables administrators to do power workload balancing and
manage power at the enclosure level. As the servers run, the
demand for power varies for each server. Dynamic Power
Capping constantly monitors power inside the server or blade and
then automatically, and nearly instantaneously, adjusts the power
draw on the server when it reaches the maximum allocated
capacity. This means users can control how much power a
particular server blade enclosure is going to use and more
accurately allocate that capacity within the datacenter.
Power-aware HP Capacity Advisor, part of Insight Dynamics – VSE, allows users
workload to analyze a set of physical or virtual server workloads and
placement recommends optimal placement on underlying physical servers for
optimal power consumption.

Virtualization

Having proved themselves reliable, virtual machines (VMs) have become a staple in all modern
consolidation and optimization projects. In addition, they allow administrators to isolate and
encapsulate an entire OS environment. In fact, the term server virtualization is commonly used as a
synonym for virtual machine technology and its software-layer abstraction.
All ProLiant c-Class server blades include the unique Virtual Connect technology that abstracts and
partitions the server-to-network I/O connections, and some server blades have been specifically
designed for virtual machine deployments with capabilities for large memory footprints, large
networking bandwidths, and easily expanded storage capabilities.
Because of their flexibility, BladeSystem servers provide a natural platform for virtual machine
implementations:
• Hardware redundancy and availability
• Embedded intelligence with Integrated Lights-Out management and Onboard Administrator
• Capabilities for large memory, processing, and I/O footprints
• Wide range of storage options including boot-from SAN, shared storage, direct-attached hot-plug
SAS drives, and Smart Array Controller options
• Power management tools:
– Power meter for monitoring server power consumption use
– Power Regulator for higher server efficiency
– High-efficiency power supplies
– Dynamic Power capping for provisioning power to groups of ProLiant servers
– – HP Thermal Logic (for monitoring and managing BladeSystem servers)
8 Because server virtualization has come to refer to virtual machine technology, HP is moving toward the use of
"machine abstraction" and "logical servers" to describe virtualized servers, regardless of whether the
virtualization technologies are hardware-based or software-based.
